Pseudoparodiella

Pseudoparodiella F. Stevens, Illinois Biol. Monogr. (Urbana) 11(no. 2): 14 (1927).

 Index Fungorum number: IF 4467; Facesoffungi number: FoF 00906, 1 morphological species (Species Fungorum 2022), no molecular data available.

Parasitic on leaf surface of dicotyledonous plants. Sexual morph: Ascomata small-sized, scattered or gregarious, superficial, globose, setiferous on surface. Peridium thin, composed of a few layers of lightly pigmented thin-walled cells of textura angularis. Hamathecium composed of rare, 2–3 μm broad pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate dehiscence not observed, obclavate, with a short, thick, knob-like pedicel, with an ocular chamber. Ascospores 2-seriateand partially overlapping, broadly fusoid to ellipsoidal with broadly to narrowly rounded ends, olivaceous to pale brown, uniseptate, constricted at septum, with upper cell slightly longer and broader than lower one. Asexual morph: Unknown.

Type species: Pseudoparodiella vernoniae F. Stevens

Notes: Pseudoparodiella resembles Acantharia in having smaller ascomata with or without pseudoparaphyses, obclavate asci and uniseptate, olivaceous brown ascospores. Pseudoparodiella differs from Acantharia in having mature pale brown ascospores. Sivanesan suggested Pseudoparodiella as the teleomorph of Spilodochium but this has not been confirmed by molecular data and requires further investigation. Zhang et al. (2011) placed Pseudoparodiella in Venturiaceae based on morphology.
